(Cl..140-'-98) This invention has for its object to provide an apparatus for resetting and levelling theteeth in card clothing. I 1 y The nature and objects of the invention will appear more fully from the accompanying description and drawing andwill be particularly pointed out'in the claims."

The apparatus of this invention may be used by itself or as an auxiliary to any other apparatus such. as a machine for mounting card clothing upon a roll and in the drawing it is conveniently with such a card roll mounting machine.

In the drawing:

Card clothing, as'is well known,.is extensively employed for various purposes, particularly on the surface ofthe drums and rolls of carding machines and similar fibre working machines. The type of card clothing with which this invention is par 'ticularly concerned comprises a foundation or back I of woven fabric, leather, rubber, or other material or suitable combination of materials and a plurality of teeth 2 formed of wire. The wire forming these teeth is usuallybent into the form of a staple and is secured in the back of the card clothing by being inserted through the back surface. These teeth extend in an inclined direction to the back, as shown in Fig. 3, and at their ends are usually bent in a reversed inclination.

The teeth are closely set in the back so that the working surface of the card clothing is thickly covered with the points of the teeth.

It is very important that, when the card clothing is mounted in place upon the roll or other element of the machine in which it is used, the

working surface shall extend throughout with great uniformity. In the case of a roll this surface must be accurately concentric with the axis of the roll. In order to secure this result, the ends of the teeth are accurately ground after the card clothing has been manufactured and again,

after the card clothing is mounted in place upon the roll or other device, it is again ground or finished to give the desired uniformity.

It islalso highly important that the-teeth. shall not be displacedinor from the back of the card clothing. In the manufacture. ofcard clothing, it is carefully inspected at the conclusion of the manufacturing operation and any-missing or mis' placed teeth replaced or reset by hand. 1

Such card clothing is commonly furnished in strips of different widthsknown as fillets and applied to the roll or'other surface of the machine in which: it is to be used in various ways; The

' main object of the present invention is to'provide an apparatus which will reset any teeth in the card'clothing which'have been partially displaced so that they protrude more or less from the back. Such an apparatus may be used; by itself, to .run card clothing through or it'may be usedasillustrated' in the drawing in connection with: another apparatus such as a machine for mounting a fillet of card clothing on the rollof a carding orv similar machine. I

The :apparatus of'the invention-consists essentially of a roll 3 preferably of a width at least equal to the width of the strip or fillet of card clothing andin'the'best and preferred form of the invention having its periphery formed with smooth rounded corrugations 4 extending transversely thereof; The fillet 5 of card clothing isfed to this roll with-the back of .the clothing in close engages ,PATEDNTVPOFFICE mentwithtthe roll'peripheryandthe roll iszdriven with a peripheral speed greater than the speed of the feed and the clothing is guided to the roll with the inclined portion 6 of the teeth in the back extending in the direction of feed. The result is that any teeth, the bases of which project below the back of the clothing, are drivenin place and reset by the frictioning action of the roll periphery and particularly of the periphery.

In the construction illustrated the roll 3 is carried by a shaft 1 journalled in a suitable frame 8. This shaft at one end has mounted thereon a small pulley 9 and this pulley is driven by a belt it running over a large pulley II which is rotated at the required speed by any suitable means. fillet of card clothing is guided over the periphery 4 of the roll 3 with the inclined portion 6 of the teeth projecting in the direction of feed and this forward feed of the fillet may be effected by any suitable means. As pointed out, the peripheral speed at which the roll is driven is greater than the speed of the forward feed of the fillet of card clothing.

corrugated roll The.

If, as is usually the case, the weight of the card the roll periphery, suitable means are provided for maintaining such close engagement, that is, with the card clothing pressed against the roll periphery. For this purpose in the construction illustrated the fillet 5 of the card clothing is' is shownas employed as auxiliary to an apparatus for mounting the fillet of card clothing on the roll of a carding machine. Such an apparatus, a portion of which is illustrated,- comprises a main frame IS, a sectional or conical roll IT, a guide box l8,-and a yielding take-up arm I 9. In this type of apparatus the forward end of the fillet is attached to the roll upon which it is being mounted and consequently asthat roll is revolved, the fillet of card clothing is fed forward in the direction of the arrow 20.' This causes the conical roll I! to rotate and, in the case illustrated, the driving pulley II is mounted on the shaft 2| of this roll I! so that it is driven thereby. Thus it will be seen that as the roll 3 is rotated with its periphery moving at a greater speed than the forward feed of the fillet of card clothing pass ing thereover, the teeth are leveled up and if any project through the back, they are driven and reset by the action of the roll periphery.

There is thus presented a very simple and efficient piece of apparatus by which the teeth in card clothing-are reset and leveled upinto accurate position in the back of the card clothing and such an apparatus may be used either as a unit by itself or as auxiliary to another piece of apparatus such as the card roll mounting apparatus illustrated.

Having thus described the invention, what is claimed'as new, and desired to be secured by Letters Patent, is: i

1. An apparatus for resetting the teeth of card clothing comprising a roll .over which the card clothing is fed with the back of the clothing in engagement with the roll periphery, means for maintaining the back of the card clothing pressed against the roll periphery, and means for rotating the roll in the direction of the feed of the card clothing at a peripheral speed greater than the speed of the'feed, whereby any teeth the bases of which project below the back of the clothing are driven in place and reset.

2. An apparatus for resetting the teeth of card clothing comprising the construction defined in claim 1, in which the roll is provided with smooth rounded corrugations extending transversely of its periphery.

' 3. An apparatus for resetting the teeth of card clothing in which the teeth are in the form of wire staples inserted from the back of the card ,clothing in an inclined direction comprising a roll over which the card clothing is fed with the back of the clothing in engagement with the roll periphery, means for guiding the card clothing to the roll with the inclined portion of the teeth in the back, extending in the .direction of'feed, means for maintaining the back of the card clothing pressed against the roll periphery, and means for rotating the rollxin the directionof the feed of the card clothing at a peripheral speed greater than the speed of the feed, whereby any teeth the bases of which project below the back of the clothing are driven in place and reset. c

4. An apparatus for resetting the teeth of card clothing comprising the construction defined in claim 3, in which the roll is,provided with smooth rounded corrugations extending transversely of its periphery. a a 5. An apparatus for resetting the teeth of card clothing comprising a roll over which the card clothing is fed with the'back of the clothing in close engagement with the roll periphery, and means for rotating the roll in the direction of the feed of the card clothing at a peripheral speed greater thanithe'speed of the feed, whereby any teeth the'bases of which project below the back of the clothing are driven in place'and reset.

6.'An apparatus for resetting the teeth of card clothing comprising the construction defined in claim 5, in which the roll is provided with smooth rounded corrugations extending transversely of its periphery.
